Yes, I clicked on the same discord link. It says, invalid invite.temp.png

That's weird. Try this one: https://discord.gg/xwsvZY.

Checked your account @puregrace. You should be removed from the blacklist by the next 10 mins.

This discord link is also not letting me in.
Ok, thanks for removing me from the blacklist.

Something is definitely wrong with your Discord or some weird settings. Just tried both links and they worked perfectly.

I am into so many discords. Anyways, let me check again.
Updated: Got it solved. I was member of 100 discord servers. So, I can't enter more. So, I left one server and joined yours. Am happy!
